This invention com rises subject matter set forth in my co-'pening application Ser. No. 200,515, filed June 22, 1927, of which this application is a division. 4

The specific devices shown are two forms of containers for materials to be refrigerated, both primarily adapted for liquids, but the novel features of the invention maybe practised in connection with other materials." The preferred refrigerant herein vselected is, solid carbon dioxide.

An' important feature of the invention is having the refrigerant (physically within and surroundedbythe pro ucts to be refri erated, yet completely cut off from all possi ility of mingling of gas from the solid carbon dioxide with the product to be refrigerated.'

I have discovered that when so located, and

particularly in connection with liquids, great economies in the use ofthe refrigerant may be eii'ected. One important contributing factor is the use of cartridges or containers filled with the solid carbon dioxide and constructed so as to it within the refrigerant 'i containing element of the device while yet separated and insulated therefrom.

i The above 'and other features of my invention will be more fully understood from the following description inconnection with -the accompanying'drawing, in which Fig. 1 is a side view of a bottle construct-4 ed in accordance with this invention;

Fig. 2 is a vertical section of the invention as applied to a water cooler; and

Fig. .3 is a side elevation of the refrigerant cartridges.

In Fig. 1 the refrigerating apparatus is shown in the form of a bottle 1, for milkor other liquid, provided with a,y central chalu-A ber 2 having a plugable entrance 3. In the present case, the plug 4 is shown as screw threaded. The bottle may be covered with an unbreakable cage to protect the glass or similar fragile material-from which bottles Y are customarily made. The central chamberv 2 extends upwardly from the bottom, being integral therewith, and the solid carbon dioxide, preferably in cartridge form, may be inserted through the entrance 3, and retained chamber 2 y replacing plug 4.

With the preferredrefrigerant, solid carbon dioxide, the gas sublimating therefrom may in intimate heat transfer relation thereto,

yet separated therefrom by a water-tight, gas-tight, impervious wall.

As will be `evident from Fig. 2 hereof and from the other forms shown in my said prior be vented in any of the usual Ways as by application, the refrigerant container 2 as well as the exterior enclosing container may be varied widely as to size, proportions and sppciic details of construction. A bottlev li e that shown in'Fig. 1 is adaptable'for a babys milk bottle, in which case the re1 frigerant will of course be removed and the bottle warmed in the usual ways before using. Y

In the water cooler shown in Fig. 2 the entrances to both the refrigerant container and thev refrigerator chamber are in the same end of the unit. This form is particularly adaptable in .the larger refrigeratory con-n tainers, especially those of the water bottle type. The bottle 11 has the opening 12 for the water and the central opening 13 for theI axially extending refrigerant container 14: which may be charged with to the refrigerant container 14 is closed, as by a plug 15, which may have leaks or a vent for escape of the gas, asin the case of Fig. 1. In use, the bottle is inverted on supporting stand 16equipped with a faucet 17 which is supplied with water through opening 12, from container 11.

Obviously,the proportions of the refrigerthe refrigerant i 'in cartridge or otherform. The entrance 1 ant container and the liquid container may be varied to suit different conditions of use and the solid carbon dioxide may be employed 'i in any desired form, but there are certain advantages in having hereinafter described.

The cartridges for the solid carbon dioxide are separately claimed in my application Ser.

No. 437,788 of even date herewith, but they the special cartridges oxide gas,

are of special importance in combination with refrigerant containers located in direct heat ,transfer relation with freezable liquids or end thereof sufliciently to telescope over thev end of another similarly constructed container. This permits of securing a plurality of such cartridges in one unit and at the same time allows for very quick and convenient Separation of the unit or any part of it.

As stated in my said parent application, these cartridges, `particularly when filled with solid carbon dioxide or the like, are preferably made of such size as to fit within the various chambers in which they are to ,be used as the refrigerant. Obviously, it is only the outer circumference of the projecting rings 7 that can thus fit said containers and this is of advantage because it affords a relatively small area of direct conducting contact, most of the cartridge being spaced away from the chamber wall and, in use, the space is necessarily filled with the evaporated carbon diwhich is a remarkably effective non-conductor of heat. This has the obvious advantage of preventing too rapid sublimation of the solid carbon dioxide, thereb avoiding waste of the refrigerant while at the same time avoiding over-refrigeration of the liquid or other material which is to be cooled thereby. f

The refrigerants act to keep the contents l of the bottles cold and natural circulation of the liquid will tend to prevent over-refrigeration thereof. The various plugs may be cork lined, and may be of the screw type. l
